Panic Output

Expected Behavior

ID should be the ID of the routing table, not a complex variable containing the ID for the VPC and the routing table.

Actual Behavior

ibm_is_vpc_routing_table..id == "/

This causes an issue when you use the newly created routing table and want to add routes to it. You need to split the ID apart from the route table before you can use it for a route.

Hi @smathews There is field with routing_table which stores the id value, please use ibm_is_vpc_routing_table.test_route_rt.routing_table instead of routing_table = split("/", ibm_is_vpc_routing_table.transit.id)[1] Thank you Sunitha

@smathews Can you please verify as suggested above and confirm us ?

@smathews is this good to close ?

[smathews]

Thanks all. It does work. However, it does not match with the schemas of the other VPC resources.

[deepaksibm]

Child resources have id in the format of / across other resources. Root level resources will have just the id of its own. Thanks for confirming.
